PIPE-G OUPLING.Y

SPECIFICATION forming part of Iletters Patent No. 522,005, dated June26, 1894.

Application filed February Z7, 1894:. Serial No. 501.644. (No model.)

To all whom it may concern:-

Be it known that I, JOHN J. BURKE, acitizen of the UnitedStates,residingfat Bualo, in the county of Erie and State of New York,

have invented a new and useful Improvement in Pipe-Couplings, of whichthe following is a specification. n j

This invention relates to couplings which lare more particularlydesigned for connectlo ing water pipes with the flushing rim ofporcelain water-closet bowls. The flushing rim of a Water-closet, asordinarily constructed, is provided with a laterally projecting horn ornipple of sufficient length to permit a metallic bushing to be securedthereto, and to this bushing the water pipe is coupled in any suitablemanner. The horn of the water closet is frequently broken oft' owingprincipally to the settling of the floor on which the closet issupported, which renders it impossible to again connect the water pipethereto in the ordinary manner.

The object of my invention is to provide a simple and inexpensivecoupling whereby the water pipe can be readily and reliably secured tothe bowl in case its horn or nipple is broken off.

In the accompanying-drawings: Figure 1 is a fragmentary vertical sectionshowing a water pipe connected with the bowl of the water closet by myimproved coupling. Fig. 2 is a transverse section in line 2--2, Fig. 1.Fig. 3 is a fragmentary section showing the i manner of introducing theattaching hooks 5 5 into the iiush opening of the bowl. FigA is aperspective view of one of the attaching hooks. Fig. 5 is a longitudinalsection, at right angles to Fig. 1, of the coupling sleeve, the lockingsleeve and one of the attaching hooks.

Like letters of reference refer to like parts in the several figures. g

A represents the bowl of a water closet which is provided at its topwith the usual hollow flushing rim B having an inlet or Hush opening bon its outer side and a row of outlet perforations b'.

C represents acoupling sleeve arranged adjacent to the outer side of theIiushing rim, 5o axially in line with its inlet opening, and

` provided with internal and external screwthreads c c respectively. Thecoupling sleeve is also provided internally, on diametrically oppositesides, with longitudinal grooves or recesses, d d. 5 E E representattaching hooks whereby the coupling sleeve is connected with theflushing rim. These hooks engage against the inner edge of the inletopening b of the iiushing rim, and their Shanks e are arranged partly 6oin said opening andpartly in the recesses of the coupling sleeve. Theinner sides of the hook Shanks are arranged flush with the inner side ofthe coupling sleeve and are provided with sectional screw-threads e ofthe same size and pitch as the internal screw thread of the couplingsleeve, so that the screw threads of the shanks form continuations ofthe internal screw threads of said sleeve. 7o

F represents a locking sleeve, whereby the attaching hooks and thecoupling sleeve are secured together. This locking sleeve is providedwith an external screw thread f which engages with the internalscrew-threads of the coupling sleeve and the hooks, thereby holding thehooks and the coupling sleeve against longitudinal movement upon eachother. The locking sleeve is provided at its outer end with notches f inwhich asuitable 8o wrench is inserted for turning the locking sleeve.The latter is provided at its front or inner end, with a plain taperingportion or extension f2 which supports the attaching hooks in aninwardly inclined position, in passing them through the inlet opening ofthe flushing rim.

G represents a packing ring arranged between the coupling sleeve and theflushing rim, and H is an internally screw-threaded 9o clamping ringarranged upon the external screw-thread of the coupling sleeve andpressing the packing ring against the iiushing rim, for producing awater-tight joint.

I represents the water supply pipebearing with its end against the outerend of the coupling sleeve. This pipe is drawn against the adjacent endof the coupling sleeve by the usual union or connection J.

In assembling the parts, the locking sleeve roo is screwed partly intothe coupling sleeve and the screw-threads at the outer or rear ends ofthe attaching hooks are then engaged with the first thread at the frontend of the locking sleeve, as shown in Fig. 3. WVhen thisis done, theattaching hooks cannot become detached from the locking sleeve but canbe tipped toward each other on the locking sleeve, sufficiently topermit them to be passed through the inlet openingof the flushing rim inwhich position they are sustained by the tapered front portion of thelocking sleeve, as represented in Fig. 3. After passing the hooksthrough the inlet opening, the locking sleeve is screwed farther intothe coupling sleeve and upon the shanks of the hooks which causes thelatter to move outward into the recesses of the coupling sleeve and to`spread Within the flushing riin, so that they extend outwardly beyondthe edge of the inlet opening. The packing ring is next pressed againstthe outer side of the iiushing rim by the clamping ring H, whereby thecoupling sleeve is drawn away from the iiushing rim and the attachinghooks are firmly drawn against theinner side of the iiushin g rim,forining aWater-tight joint between the coupling sleeve and the fiushingrim. The Water pipe is finally connected with the coupling sleeve by theunion J, in the ordinary manner.

I claim as my invention-- 1. The combination With the coupling sleeve ofthe coupling sleeve and the attaching hooks, substantially as set forth.

2. The combination with the coupling sleeve provided on its inner sidewith a screw-thread and longitudinal grooves extending through saidthread, of attaching hooks having Shanks arranged in said grooves andprovided with sectional screw threads which correspond With the internalscrew-thread of the coupling sleeve and alocking sleevehaving a taperingfront portion, for supporting the attaching hooks in an inclinedposition, and an externally screw-threaded rear portion which engageswith the screw-threads of the coupling sleeve and the attachinghooks,substantially as set forth.
